    Our setup is as follows. We have an exchange server which forwards mail for particular domains to postfix for address rewriting. Postfix re-writes the sender domain address and forwards the mail down a private link. For example exchange sends mail to postfix with a sender address of [email protected] postfix rewrites the sender address as [email protected] and then forwards the mail.

    I have a need to rewrite the return path\address of all mail received from a pspecific address while still re-writing the sender domain as explained above before being forwarded by postfix.

    There are no local mailboxes on postfix. Postfix simple recieves mail re-writes the sender domain and forwards.

    Having read other posts I believe this can be done by using a different submission interface in postfix - but I have no idea how to do this.

    This is what I have seen on another site:

    The right solution is to use a different submission interface, that
    lets you set the envelope sender. For example:

    echo "EHLO $(uname -n)"
    echo "MAIL FROM:<com>"
    echo "RCPT TO:<org>"
    echo "DATA"
    echo "From: <com>"
    echo "To: <org>"
    echo "Reply-To: <com>"
    echo "Subject: the information you requested"
    echo ""
    perl -pe 's/^\./../' /some/path/to/msg-body
    echo "."
    echo "QUIT"
    ) | /usr/sbin/sendmail -bs

    Where in postfix would I create a new submission interface and is the above information the correct way to change the return path?

    Any and all help appreciated.

    Many Thanks
